Dear All, I posted the class notes from today: http://www.cs.dartmouth.edu/~sergey/cs59/ruby/ruby-compiler-and-vm-code.txt and the various Rudy examples done in class, sorted by time, in http://www.cs.dartmouth.edu/~sergey/cs59/ruby/?C=M;O=D (These examples should be covered by Ch. 1--3 of your Ruby book) Please note the suggested LISP exercises in recursive functions---similar (but harder) problems will be in the next homework and the midterm. I will be posting the extra-credit x86 exercises later tonight or tomorrow morning. Thank you, --Sergey
